1 Safety Precautions   

 

(1)  This product can’t be installed at corrosive, inflammable or explosive environment or the 

place with special requirements, such as kitchen. Otherwise, it will affect the normal 
operation or shorten the service life of the unit, or even cause fire hazard or serious injury. As 
for the above special places, please adopt special air conditioner with anti-corrosive or 
anti-explosion function. 

(2)  Follow this manual to complete the installation work. Please read this manual carefully 

before turning on or repairing the unit. 

(3)  Installation should be conducted by the dealer or qualified personnel. Please do not attempt 

to install the air conditioner by yourself. Improper installation may lead to water leakage, 
electric shock or fire hazard, etc. 

(4)  Before installation, please check whether the power supply is complied with that specified on 

the nameplate and check the safety of the power supply.   

(5)  The air conditioner must be grounded reliably for avoiding electric shock. Please do not 

connect the earthing wire to gas pipe, water pipe, lightning rod or telephone line. 

(6)  Be sure to use special accessories and parts for installation to prevent water leakage, 

electric shock and fire hazard, etc. 

(7)  If refrigerant leakage happens, please ventilate the room immediately.   

(8)  Diameter of power cord should be large enough. The damaged power cord and connection 

wire must be replaced with special cables. 

(9)  When the power cord is connected, please fix the electric box cover properly to avoid safety 

accidents. 

(10) Never fail to comply with the nitrogen-charging welding process. Do charge nitrogen when 

welding the pipes.     

(11) Never short circuit or cancel the pressure switch to prevent unit damage.   

(12) As for the unit controlled by the wired controller, connect the wired controller well firstly and 

then energize the unit; otherwise, the unit can’t operate normally. 

(13) When installation is finished, please check whether the drainage pipes, pipelines and electric 

wires are connected correctly to avoid water leakage, refrigerant leakage, electric shock or 
fire, etc. 

(14) Do not insert fingers or objects into air outlet or air return grille. 

(15) Open the door and window frequently to keep good ventilation for avoiding oxygen deficit 

when gas heater or oil heater is used in the room. 

(16) Never plug in or unplug the power plug directly to turn on or turn off the air conditioner.   

(17) Once the air conditioner is turned on, it can be turned off only after it has operated for 5min 

at least; otherwise, it will affect the oil return of compressor. 

(18) Do not allow children to operate this air conditioner. 

(19) Do not operate this air conditioner with wet hands. 

(20) The air conditioner can be cleaned only when it has been turned off and the power has been 

cut off; otherwise, it may cause electric shock or injury. 

(21) Never spray or flush water towards the air conditioner; otherwise, malfunction or electric 

shock may happen. 

(22) Do not expose the air conditioner to the moist or corrosive environment. 

(23) Put through the power 8 hours in advance before operation. Do not cut off the power when 

the air conditioner stops operation for only about one night (protect the compressor).   

(24) Volatile liquid, such as diluent or gasoline, will damage the appearance of air conditioner. 

Only soft dry cloth and wet cloth dipped with neutral detergent can be used to clean the outer 
case of air conditioner.
